power from non USB source

I want to power my Alchitry AU from my own PSU, but I’d still like to be able to debug it when I need.
It looks like removing the large diode on the underside near the USB connector would allow me to do this (I checked the schematics).
Could you confirm that’s the case please?

You don’t need to modify the board at all. The diode is there to protect the USB port from reverse voltage if you power it externally.

You can simply connect 5V to the 0.1" holes or through the main connectors via an element.

That’s great, many thanks :slight_smile:
